/// @brief
/// DomainParticipant events Listener
///
/// Since a DomainParticipant is an Entity, it has the ability to have a Listener
/// associated with it. In this case, the associated Listener should be of type
/// DomainParticipantListener. This interface must be implemented by the
/// application. A user-defined class must be provided by the application which must
/// extend from the DomainParticipantListener class.
///
/// <b><i>
/// All operations for this interface must be implemented in the user-defined class, it is
/// up to the application whether an operation is empty or contains some functionality.
/// </i></b>
///
/// The DomainParticipantListener provides a generic mechanism (actually a
/// callback function) for the Data Distribution Service to notify the application of
/// relevant asynchronous status change events, such as a missed deadline, violation of
/// a QosPolicy setting, etc. The DomainParticipantListener is related to
/// changes in communication status StatusConditions.
